This was with ghc-8.10.3

Hmm actually this may well be a stackage build issue.

[ysangkok]

I don't think it's a Stackage issue, it is more likely an issue with the doctest setup, since it doesn't consider environment files and it doesn't use cabal-doctest either. The tests pass if run with the new REPL invocation mode available in doctest-0.20.1:

cabal repl --with-ghc=doctest --ghc-options="-XQuasiQuotes -XOverloadedStrings"

And the package could be added back to Nightly when #65 is merged. The Stackage CI probably can't run the doctests, but that isn't a huge issue to me.

[ysangkok]

@Porges I see you removed doctest as a build dependency in recent commits. Would it be possible to make a release? Then Stackage wouldn't need to make an exception for

[Porges]

@ysangkok This is now done.
